removing drive from unraid (without replace)

Featured Replies

Hello!

I am trying to remove a drive from my unraid without replacing it. There is still data on the drive.

I tried the method described in the wiki at http://lime-technology.com/wiki/index.php/FAQ_remove_drive but I cannot run the rsync command while the array is offline... and it seams pointless when it is still runnning since the /mnt/user includes data from my drive...

Any ideas/suggestions?

Thanks

Tobias

Depending on how the allocation method is setup, it may go onto another drive if you rsync from the disk to the usershare.

 

not 100% sure, but i would assume you could rsync it directly to a drive if the usershare doesn't work?

allocation method is high water

 

can't I somehow move everything to a different drive, remove the obsolete disk and run parity build again?

You could copy the data off the drive copying within the server from disk to disk (from /mnt/disk? to /mnt/disk?). That way you can empty the drive, then remove it and recreate parity.

will this command work?

cp /mnt/disk3/* /mnt/disk4/

I would use 'mc' (midnight commander).

 

With the two pane operation it is easy to see what and where you are copying.

You could go to the disk and rename the top level directory so the data does not appear in the user share any more. Then, you can rsyc to the user share. Make sure to exclude the disk from the user share first.

Second that.... easy, looks like windows, you see progress and you see what you do...

 

This could by the way also be a very good addon for a future version "empty drive", such a command would:

 

- remove the drive from all user-shares

- copy all the data back to the user-shares (that way it will end up on other drives

 

Disk could then be safely removed and parity reset

running 'mc' command right now. So far so good  ;)
